A timing control component is installed on the top of the top plate 11. The timing control component is used to control the time of hot water discharge. The timing control component includes a control box 12 and a timer 13. The timer 13 is installed on the front of the control box 12. A switch component is installed through one side of the waste heat recovery box 1. The switch component includes a hot water outlet pipe 4 and a first solenoid valve 5.

[0025] The waste heat recovery box 1 is used to provide space for heat exchange and also provides an installation position for the switch component. After the waste hot water enters the waste heat recovery box 1, the control box 12, the timer 13 and the first solenoid valve 5 are electrically connected. The timer 13 can control the switching time of the first solenoid valve 5 through the control box 12 to close the first solenoid valve 5, so that the hot water in the waste heat recovery box 1 will not be discharged through the hot water outlet pipe 4, and the waste water will remain inside the waste heat recovery box 1, so that the device can perform heat exchange for a longer time and with higher heat exchange efficiency.
[0026] See also Figure 1 and Figure 3 , an embodiment provided by the utility model: a waste heat recovery economizer of a waste heat recovery device;
[0027] It includes a circulation pipe 8, a base 2 is installed at the bottom of the waste heat recovery box 1, a hot water inlet pipe 3 is installed through the other side of the waste heat recovery box 1, a cold water inlet pipe 10 is installed through the front of the waste heat recovery box 1, a support frame 7 is installed inside the waste heat recovery box 1, a circulation pipe 8 is installed on the inner side of the support frame 7, the top end of the circulation pipe 8 passes through the top of the top plate 11, the other end of the circulation pipe 8 is connected to the cold water inlet pipe 10, and an insulation layer 9 is installed inside the waste heat recovery box 1;
[0028] The base 2 is used to protect the bottom of the waste heat recovery tank 1. The waste hot water enters the interior of the waste heat recovery tank 1 through the hot water inlet pipe 3. The circulation pipe 8 used for heat exchange is fixed to the interior of the waste heat recovery tank 1 through the support frame 7. Cold water enters the interior of the circulation pipe 8 through the cold water inlet pipe 10, so that the hot water in the waste heat recovery tank 1 heats the cold water in the circulation pipe 8.
[0029] See also Figure 1 and Figure 4 , an embodiment provided by the utility model: a waste heat recovery economizer of a waste heat recovery device;
[0030] It includes a transmission pump 14 and a second solenoid valve 18. The transmission pump 14 is installed on the top of the top plate 11.

At this time, the discharged water temperature is the highest. The hot water that continues to be discharged is discharged through the third solenoid valve 20 and the second solenoid valve 18 is closed, so that the subsequent transmitted hot water is discharged through the third discharge pipe 21, so that the heat of the hot water discharged after the heat exchange is different, so as to facilitate the use of hot water at different temperatures. The second solenoid valve 18 and the third solenoid valve 20 are both set and controlled in advance by the timing control component.
[0032] Working principle: Before using the waste heat recovery economizer, you should first check whether there are any problems that affect the use of the waste heat recovery economizer.
